[PATCH AUTOSEL 4.19 01/83] backlight: pwm_bl: Fix devicetree parsing with auto-generated brightness tables

by Sasha Levin

From: Heiko Stuebner <heiko.stuebner(a)bq.com> [ Upstream commit 61170ee9386888f1e6f7e9cc58e8d9a8c2a3c1dd ] Commit 88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED linearly to human eye") made the parse-dt function return early when using an auto- generated brightness-table, but didn't take into account that some more settings were handled below the brightness handling, like power-on-delays and also setting the pdata enable-gpio to -EINVAL. This surfaces for example in the case of a backlight without any enable-gpio which then tries to use gpio-0 in error. Fix this by simply moving the trailing settings above the brightness handling.
